Bridge plug with selectivity opened through passage

A completion method, comprising:

• delivering a plug on a wireline with flow into a borehole;
• setting said plug at a desired location where existing formation access into the borehole is isolated on one side of said plug such that a tubular string that isolates the formation on an opposite side of said plug can be pressure tested;
• initially raising pressure against an uphole side of said plug in the borehole to a first pressure to conduct a pressure test of the tubular string;
• further raising pressure to a higher pressure than said first pressure to remove a barrier from a passage through said plug;
• pumping fluid through said passage of the still set plug to deliver at least one tool for another operation on said uphole side of said plug.
